    Add 8 to both sides and use quadratic equation.

    Perhaps you're seeing a pattern by now, that the answer is to isolate all terms on one side and use the quadratic equation

    add 8 to both sides 2x^2 +3x + 8 = 0 we can't factor this, so we have to use the quadratic formula |dw:1323577700376:dw| plug it in basically. -3 (+-) \[\sqrt{3^2-4(2)(8)}\] --------------------------- 2 * 2
